What is Heap Memory?

The term ‘Heap Memory’ refers to a section of computer memory which is usually utilised in dynamic allocations. This means that these blocks of memory can be occupied and vacated in any random order and accessed a number of times, which is the exact opposite of ‘Stack Memory’ which is allocated on a last in, first out basis.

Heap memory needs to be specifically ‘deallocated’ when data is no longer required and this process is referred to as ‘garbage collection’. Programming languages that feature manual garbage collection require the programmer to write specific code that instructs the release of data when it is no longer needed.

What is Spin-Transfer Torque Memory?

Spin-Transfer Torque is a technique that is used in MRAM or to give it its full name - magnetic random access memory to reduce energy consumption and improve performance. This tech is able to be used to change the state within MRAM, which it does by ‘flipping’ the active elements with magnetic fields and has the added advantage of improved scalability.

The Spin Transfer Torque was released as a commercial application by Everspin technologies in 2012 which came in the form of a 64 Megabyte Dual Inline DDR3 STT-MRAM module. This launch followed a very busy few years for STT-RAM, with a number of different parties researching the technology.

Hynix, Grandis, Hitachi, Qualcomm and Russian backed Crocus Technology have all invested a lot of time and funding into the concept, as you’ll see from the timeline below:

2008Grandis and Hynix Semiconductor joined forces to explore the viability of STT-RAM

2009A 32 Megabyte STT-RAM module was demonstrated jointly be Tohoku University and Hitachi

2011Grandis bought out by Samsung for an undisclosed fee

Qualcomm announce a 1 MB ‘Embedded’ STT-MRAM module

Investment of $300m made in Crocus Technology by Russian Nanotechnology Corporation who built a factory to produce MRAM hardware in Moscow

ProgressThe aforementioned factory was built and began its first production line of wafers in late 2014. Fast forward to 2018 and Everspin is currently focussing on the 256 STT-MRAM module, illustrating just how far the technology has come in a very short space of time.
